Description

Technical Field

[0001] The present application belongs to the field of lighting technology, and more specifically, relates to a film and television lamp. Background Art

[0002] In video, film, television, and photography scenes, cinema lights are often used to fill in or set the lighting for the subject or scene. When using cinema lights, it's often necessary to install accessories like softboxes or lens hoods on the light-emitting side of the lights.

[0003] Currently, cinema lights are equipped with a push rod mechanism. Once an accessory is mounted on the light-emitting side of the light, the push rod of the push rod mechanism can lock the accessory to prevent it from falling off the light. The push rod mechanism's operating portion extends from the side of the light toward the accessory. To remove the accessory, the push rod mechanism's operating portion can be manually pushed to disengage the push rod from the accessory, thereby removing the accessory from the light.

[0004] However, when the size of the accessory is large, the accessory will block the operating portion of the top rod mechanism after being installed on the light-emitting side of the movie light, causing inconvenience in removing the accessory. Summary of the Invention

Thus, when the phrases "in one embodiment" or "in some embodiments" appear in various places throughout this specification, not all references are to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0050] As described in the background art, in the prior art, when a large accessory is installed on the light-emitting side of a movie light, it will block the operating portion of the top rod mechanism, causing inconvenience in removing the accessory.

[0051] In order to solve the above problems, the present application embodiment provides a video light, please refer to Figure 1-Figure 7 The movie light comprises a housing 1, a push rod 2, and a bracket 3. The housing 1 has a first through hole 111, whose axis is parallel to the light's emission direction. The housing 1 also has a second through hole 121, the axis of which is at an angle to the axis of the first through hole 111. The push rod 2 extends through the interior of the first through hole 111 and is movable along the axis of the first through hole 111. The bracket 3 is disposed between the first through hole 111 and the second through hole 121, allowing the bracket 3 to move relative to the housing 1 between the first through hole 111 and the second through hole 121. For example, this can be achieved by pressing or pulling along the axis of the second through hole 121. Alternatively, a transition structure can be used to enable the bracket 3 to slide or rotate relative to the housing 1. The first end of the bracket 3 is provided with an inclined section 31, and the second end of the bracket 3 extends to the second through hole 121. The end of the push rod 2 facing the interior of the housing 1 is slidably connected to the inclined section 31, with the axis of the push rod 2 forming an acute angle with the plane of the inclined section 31. The acute angle here does not include 0 degrees and 90 degrees, and taking the minimum angle between the axis of the push rod 2 and the plane where the inclined section 31 is located as an example, the specific angle size can depend on the movement stroke of the push rod 2 relative to the first through hole 111, that is, it is determined by the movement stroke size of the push rod 2.

[0052] The end of the push rod 2 facing the inside of the shell 1 is slidably mounted on the inclined section 31. It is worth mentioning that the second end of the bracket 3 is used to receive external force to make the bracket 3 move relative to the shell 1 along the axis parallel to the second through hole 121. When the bracket 3 moves, it drives the end of the push rod 2 facing the inside of the shell 1 to slide on the inclined section 31 toward the second end of the bracket 3, so as to drive the push rod 2 to telescopic movement relative to the first through hole 111. It can be understood that during the movement, there may be surface contact between the inclined section 31 and the push rod 2, which can be direct or indirect surface contact. Figure 2 For example, the inclined surface of the inclined section 31 can be inclined from right to left along the axis of the second through hole 121 (i.e., the inclined surface of the inclined section 31 faces the left side). At this time, for example, the second end of the bracket 3 can be pressed, and the push rod 2 retracts into the first through hole 111. If the bracket 3 is not pressed, the push rod 2 extends out of the first through hole 111. Figure 2 For example, the inclined surface of the inclined section 31 can be inclined from left to right along the axis of the second through hole 121 (i.e., the inclined surface of the inclined section 31 faces the right). In this case, for example, when the second end of the bracket 3 is pulled, the push rod 2 retracts into the first through hole 111. When the bracket 3 is not pulled, the push rod 2 extends out of the first through hole 111. As long as the specific tilting direction can match the actual movement direction of the bracket 3, it is acceptable. For example, the bracket 3 can also slide along the axis perpendicular to the second through hole 121, so that the component force of the inclined section 31 drives the push rod 2 to move.

[0053] In the embodiment of the present application, a first through-hole 111 and a second through-hole 121 are provided in the housing 1, and a push rod 2 is inserted through the first through-hole 111. A bracket 3 is disposed between the first through-hole 111 and the second through-hole 121, and the end of the push rod 2 facing the interior of the housing 1 is slidably mounted on the inclined section 31 of the bracket 3. To remove an accessory from the cinema light, the user can apply an external force to the second end of the bracket 3, causing the bracket 3 to move relative to the housing 1 along an axis parallel to the second through-hole 121. The component of force generated by the lateral movement of the inclined section 31 along the axis of the push rod 2 drives the push rod 2 to move relative to the first through-hole 111. This allows the second through-hole 121 to be positioned at an angle to the first through-hole 111. This prevents larger accessories from obstructing the second through-hole 121. The user can apply external force to the second end of the bracket 3 through the second through-hole 121 without interference from the accessory, making the operation easier and facilitating accessory removal.

[0054] In some embodiments, the housing 1 may include a front wall 11 and a side wall 12 surrounding the front wall 11. A first through hole 111 is provided in the front wall 11, and a second through hole 121 is provided in the side wall 12. The axis of the second through hole 121 is perpendicular to the axis of the first through hole 111. The bracket 3 includes a first connecting segment 32. The first connecting segment 32 is parallel to the axis of the second through hole 121 and is slidably connected relative to the front wall 11. The first connecting segment 32 is connected to the inclined segment 31 and is not coplanar. It is understood that the first connecting segment 32 can directly bear the force from the second end of the bracket 3 and transmit it to the inclined segment 31. In the simplest principle, the first connecting segment 32 can be a part of the second end of the bracket 3 and partially exposed relative to the second through hole 121. For example, operating the first connecting segment 32 drives the inclined segment 31 to slide relative to the push rod 2. Of course, in a more complex structure, the first connecting segment 32 can be merely a part of the bracket 3, and the bracket 3 also includes other structures described in subsequent embodiments.

[0055] It will be appreciated that the front wall 11 of the housing 1 is provided with a bayonet for securing accessories such as a softbox or lens hood. For example, the accessory may be provided with a holder that engages with the bayonet, which may be a Bowens bayonet or other multi-point bayonet. The first through-hole 111 is defined within the bayonet. When the accessory is mounted on the light-emitting side of the cinema light, the front wall 11 of the housing 1 directly faces the accessory. Once the accessory is mounted on the bayonet, the push rod 2 can be controlled to move within the first through-hole 111 so that the end of the push rod 2 facing the outside of the housing 1 extends out of the first through-hole 111 and secures to the accessory, thereby locking the accessory and preventing it from falling off the cinema light.

[0056] For example, when it is necessary to remove an accessory from the movie light, the user can apply an external force to the second end of the bracket 3, and the direction of the external force is along the axis of the second through hole 121 toward the interior of the housing 1. It can be understood that the force applied to the second end of the bracket 3 can be transmitted to the inclined section 31 by the first connecting section 32. Of course, the first through hole 111 can limit the push rod 2, that is, limit the movement of the push rod 2 along the radial direction of the first through hole 111. The push rod 2 can be provided with an inclined surface corresponding to the inclined section 31, and the inclined surface can achieve surface contact with the inclined section 31. When the bracket 3 is sliding, its inclined section 31 drives the end of the push rod 2 facing the interior of the housing 1 to slide on the inclined section 31 toward the second end of the bracket 3, and then drives the end of the push rod 2 facing the outside of the housing 1 to move to the inside of the first through hole 111 to release the lock on the accessory, thereby achieving the removal of the accessory.

[0057] In some embodiments, see Figure 5 and Figure 6 As a specific implementation of the film and television lamp provided in an embodiment of the present application, the axis of the second through hole 121 is perpendicular to the axis of the first through hole 111, so that when an external force acts on the second end of the bracket 3, the end of the push rod 2 toward the inside of the shell 1 slides on the inclined section 31 along the inclined direction of the inclined section 31.

[0058] Specifically, the axis of the second through hole 121 is along Figure 6 The axis of the first through hole 111 extends in the direction of the X axis. Figure 6 The Y-axis extends in the middle direction, and the X-axis is perpendicular to the Y-axis. The positive direction of the Y-axis is the light-emitting direction of the movie light. When an external force acts on the bracket 3, the bracket 3 can be driven to move along the positive direction of the X-axis. Under the limiting action of the first through hole 111, the end of the push rod 2 facing the inside of the shell 1 slides on the inclined section 31 along the inclined direction of the inclined section 31. When it is necessary to remove the accessories on the movie light, the user can apply an external force to the second end of the bracket 3 toward the inside of the shell 1 in a direction perpendicular to the light-emitting direction of the movie light, so as to avoid being obstructed by the accessories on the movie light during the operation of the bracket 3, thereby facilitating the removal of the accessories.

[0059] In some embodiments, see Figure 3-Figure 7The film and television light also includes a slider 4, which is connected to the push rod 2. The slider 4 can be a square block and can be fixed to the push rod 2 by fasteners such as bolts. Other detachable fixed connections such as bonding, riveting or clamping are also feasible. The side of the slider 4 facing the front wall 11 is provided with an inclined surface that is compatible with the inclined section 31, and the slider 4 is slidably connected to the inclined section 31. The inclined surface of the slider 4 can be parallel to the inclined surface of the inclined section 31. It can be understood that the inclined surface of the slider 4 can be provided with a protrusion or a slide groove, and the inclined surface of the inclined section 31 can be provided with a corresponding slide groove or protrusion. Of course, in other embodiments, the sliding connection can also be a waist-shaped hole and a protrusion, and the waist-shaped hole and the fixed column can cooperate. When an external force acts on the second end of the bracket 3, the slider 4 slides relative to the inclined section 31 to drive the push rod 2 to move relative to the first through hole 111. The slider 4 serves as an intermediate component for slidingly connecting the push rod 2 and the inclined section 31 , which can reduce the structural design complexity and cost of the push rod 2 , facilitate manufacturing and assembly, and make the push rod 2 slide more smoothly on the inclined section 31 . Figure 7 As shown, the surface of the slider 4 facing the inclined section 31 is formed as an inclined surface that matches the inclination angle of the inclined section 31. It is understood that when the slider 4 slides on the inclined section 31, the inclined surface of the slider 4 cooperates with the inclined section 31. This arrangement can make the slider 4 slide on the inclined section 31 more smoothly.

[0060] In some embodiments, the inclined section 31 is provided with a first sliding portion 311 extending along the inclined direction of the inclined section 31. The slider 4 is provided with a second sliding portion 22 that cooperates with the first sliding portion 311. The first sliding portion 311 and the second sliding portion 22 are slidably connected. The first sliding portion 311 and the second sliding portion 22 can be correspondingly matched slide rails and elongated protrusions, or fixed columns, bolts, etc., and waist-shaped holes (such as those shown in the accompanying drawings). When an external force acts on the second end of the bracket 3, the first connecting section 32 drives the first sliding portion 311 to slide relative to the second sliding portion 22, thereby driving the push rod 2 to move relative to the first through hole 111. The first sliding portion 311 and the second sliding portion 22 can also limit the sliding direction of the slider 4. At the same time, the connection between the push rod 2 and the slider 4 can prevent the slider 4 from dislodging from the inclined section 31.

[0061] For example, a set screw can be used as the second sliding portion 22, and a waist-shaped hole can be provided in the inclined section 31 as the first sliding portion 311. The set screw is mounted on the slider 4, passes through the waist-shaped hole, and is locked onto the push rod 2. The sliding connection between the set screw and the waist-shaped hole defines the sliding direction of the slider 4.

[0062] When the first sliding part 311 and the second sliding part 22 are respectively a sliding rail and a long strip protrusion that cooperate with each other, an avoidance section can be set on the slider 4, which bypasses the inclined section 31 of the bracket 3 and is connected to the push rod 2 to ensure the reliability of the connection between the slider 4 and the push rod 2.

[0063] In other embodiments, Figure 6 and Figure 7 As shown, the first sliding portion 311 can also cooperate with the push rod 2 to define the sliding direction of the slider 4 on the inclined section 31. Specifically, a waist-shaped hole can be opened on the inclined section 31 to serve as the first sliding portion 311. The end of the push rod 2 facing the interior of the housing 1 passes through the first sliding portion 311 and the slider 4 in sequence, and the slider 4 is fixed to the push rod 2 using bolts. At this time, the slider 4 is clamped between the inclined section 31 and the head of the bolt. Of course, those skilled in the art can also fix the slider 4 to the push rod 2 through other methods, such as clamping, riveting, etc., which are not limited here.

[0064] Figure 4 and Figure 7 As shown, a support section 35 is provided at one end of the inclined section 31 away from the second through hole 121. The support section 35 may be parallel to the front wall 11 of the housing 1, and one end of the first sliding portion 311 may extend onto the support section 35. It will be appreciated that when the second end of the bracket 3 is not subjected to external force, the bracket 3 can support the slider 4 via the support section 35, thereby improving the stability of the bracket 3 supporting the slider 4.

[0065] In other embodiments, a chute may be provided on the inclined section 31 and located on the side of the inclined section 31 facing the first through hole 111, with the chute extending along the inclined direction of the inclined section 31. An outwardly projecting bump may be provided on the end of the push rod 2 facing the interior of the housing 1, with the bump slidably mounted within the chute to achieve a sliding connection between the push rod 2 and the inclined section 31, although this is not intended to be a limitation.

[0066] In some embodiments, see Figure 3-Figure 7As a specific embodiment of the film and television lamp provided in the embodiment of the present application, a first guide portion 312 is also provided on the inclined section 31 and is spaced apart from and parallel to the first sliding portion 311. A second guide portion 5 is provided on the slider 4 to cooperate with the first guide portion 312, and the first guide portion 312 and the second guide portion 5 are slidably connected. The first guide portion 312 and the second guide portion 5 can be correspondingly matched slide rails and long protrusions, or fixed columns, bolts, etc. and waist-shaped holes (such as shown in the accompanying drawings) and the like. Through the mutual cooperation between the first guide portion 312 and the second guide portion 5, the sliding direction of the slider 4 on the inclined section 31 is limited, which can ensure that the slider 4 will not rotate around the axis of the push rod 2 during the sliding process on the inclined section 31, so that the inclined surface of the slider 4 can stably cooperate with the inclined section 31, thereby ensuring that the slider 4 can slide smoothly on the inclined section 31.

[0067] It should be understood that the sliding portion in this application refers to the relative sliding connection between two parts. For example, the sliding fit of a screw in a waist-shaped hole can be called the first sliding portion and the second sliding portion respectively. Of course, the sliding fit of a corresponding protrusion and a sliding groove is also acceptable. This does not mean that a single component that remains in a fixed position at a certain point is not considered a sliding portion. The corresponding guide portion can be understood in the same way and will not be described in detail here.

[0068] A screw can be used as the second guide portion 5. Accordingly, the slider 4 has an internally threaded hole that mates with the screw. The screw shaft extends from the internally threaded hole in the slider 4 and resides in the first guide portion 312. It is worth noting that the width of the first guide portion 312 matches the diameter of the screw shaft. Therefore, once the second guide portion 5 passes through the first guide portion 312, the first guide portion 312 defines the direction of movement of the second guide portion 5, thereby preventing the slider 4 from rotating about the axis of the push rod 2 during the sliding process.

[0069] In other embodiments, the second guide portion 5 may be a guide shaft integrally formed with the slider 4, the guide shaft extending into the interior of the first guide portion 312 and slidably connected to the first guide portion 312, which is not intended to be exclusive. In other embodiments, the first guide portion 312 and the second guide portion 5 may be a set, or the first guide portion 312 and the second guide portion 5 may be two sets, one located on each side of the first sliding portion 311. In some embodiments, the first guide portion 312 and the second guide portion 5 are formed by corresponding grooves and protrusions and are parallel to the length direction of the first sliding portion 311.

[0070] In some embodiments, see Figure 3-Figure 7As a specific embodiment of the film and television light provided in an embodiment of the present application, a third sliding portion 321 extending along the sliding direction of the bracket 3 is provided on the first connecting section 32. The film and television light also includes a fourth sliding portion 6 mounted on the front wall 11, and the fourth sliding portion 6 is slidably connected to the third sliding portion 321. Schematically, the fourth sliding portion 6 includes a guide portion connected to the front wall 11 and a limiting portion 61 connected to the guide portion. The guide portion is slidably connected to the third sliding portion 321. The limiting portion 61 is located on the side of the first connecting section 32 away from the front wall 11, and the width of the limiting portion 61 is greater than the width of the third sliding portion 321. The sliding portion here can refer to the description of the sliding portion above.

[0071] The guide portion of the fourth sliding portion 6 cooperates with the third sliding portion 321 on the first connecting section 32 to achieve a sliding connection between the first connecting section 32 and the front wall 11. The guide portion of the fourth sliding portion 6 can also define the sliding direction of the first connecting section 32, thereby defining the sliding direction of the bracket 3. In addition, the limiting portion 61 of the fourth sliding portion 6 can limit the distance between the first connecting section 32 and the front wall 11, preventing the first connecting section 32 from separating from the front wall 11 during the sliding process of the bracket 3 and interfering with other components within the movie light.

[0072] Figure 3-Figure 7 As shown, the first connecting section 32 is connected to one end of the inclined section 31 facing the second through hole 121. A screw can be used as the fourth sliding portion 6, the screw shaft of the screw being the guide portion, and the head of the screw being the limit portion 61. Specifically, the screw shaft passes through the third sliding portion 321 and is locked to the front wall 11. The screw shaft is slidably connected to the third sliding portion 321, and the width of the screw head is greater than the width of the third sliding portion 321 to limit the distance between the first connecting section 32 and the front wall 11. It is worth mentioning that the width of the guide portion matches the width of the third sliding portion 321 to further improve the stability of the bracket 3 during the sliding process.

[0073] In other embodiments, a sliding groove extending along the sliding direction of the bracket 3 can be provided on the side of the front wall 11 facing the first connecting section 32, and accordingly, a protrusion protruding outward is provided on the side of the first connecting section 32 facing the front wall 11. The protrusion extends into the interior of the sliding groove and is slidingly connected to the sliding groove. The sliding connection between the first connecting section 32 and the front wall 11 can be achieved through the mutual cooperation between the sliding groove and the protrusion.

[0074] In some embodiments, see Figure 1 、 Figure 4 、 Figure 6 and Figure 7As a specific implementation of the film and television light provided in the embodiment of the present application, the film and television light also includes a push button 7, which includes a pressing portion 71 and a first connecting portion 72. The pressing portion 71 is exposed relative to the second through hole 121, and one end of the first connecting portion 72 is connected to the pressing portion 71, and the other end extends inward along the axis of the second through hole 121 and is connected to the first connecting section 32.

[0075] As can be understood, the push button 7 is disposed within the second through hole 121 and is movable along the axial direction of the second through hole 121. The pressing portion 71 of the push button 7 is exposed from the second through hole 121, making it easy for the user to press the push button 7 to apply an external force to the bracket 3. The first connecting portion 72 may be a strip-shaped sheet-like structure that abuts against the inner wall of the second through hole 121, thereby improving the stability of the push button 7 as it slides within the second through hole 121.

[0076] Schematically, the bracket 3 also includes a first connecting section 32, a second connecting section 33 connected between the first connecting portion 72 and the first connecting section 32, and the second connecting section 33 is arranged at an angle to the first connecting section 32. The housing 1 is provided with a stopper 15, which is used to abut the second connecting section 33 to limit the movement of the bracket 3. The second connecting section 33 can be an "L"-shaped structure, with one end of the "L"-shaped structure connected to the first connecting section 32, and the other end of the "L"-shaped structure extending toward the side wall 12 of the housing 1. The other end of the "L"-shaped structure can be fastened to the first connecting portion 72 using multiple bolts. Therefore, when the user applies external force to the push button 7, the bracket 3 will not rotate relative to the push button 7. The abutment of the stopper 15 with the second connecting section 33 can prevent the bracket 3 from sliding indefinitely, ensuring that the movement of the entire bracket 3 is within a certain range.

[0077] In some embodiments, see Figure 1 、 Figure 4 、 Figure 6 and Figure 7 The push button 7 also includes a second connecting portion 73, one end of the second connecting portion 73 is connected to the pressing portion 71, and the other end extends inward along the axis of the second through hole 121 and is connected to the first connecting section 32. The second connecting portion 73 and the first connecting portion 72 are arranged parallel to each other along the height direction of the push button 7.

[0078] The second connecting portion 73 can be a square beam disposed below the first connecting portion 72. The side of the second connecting portion 73 away from the first connecting portion 72 can abut against the inner wall of the second through hole 121. When the first connecting portion 72 and the second connecting portion 73 respectively abut against the inner wall of the through hole, they can limit and guide the push button 7, thereby further improving the stability of the push button 7 when sliding in the second through hole 121.

[0079] Schematically, a hole for the second connecting portion 73 to pass through can be opened on the second connecting section 33 of the bracket 3. After the second connecting portion 73 passes through the hole on the second connecting section 33, it can be connected to the end of the first connecting section 32 away from the inclined section 31 by screws.

[0080] The above arrangement ensures the stability of the connection between the push button 7 and the bracket 3. When the user presses the push button 7 to slide the bracket 3, the bracket 3 is not easily deformed by external force. At the same time, the bracket 3 will not shake relative to the push button 7.

[0081] It can be understood that the surface of the above-mentioned pressing part 71 can be provided with friction lines that are conducive to pressing. The above-mentioned first connecting part 72, the second connecting part 73 and the pressing part 71 can be an integrally molded part or a split part. Of course, the inclined section 31, the first connecting section 32, the second connecting section 33 and the bending section 34 can be an integrally molded part or a split part, which is not limited here.

[0082] In one embodiment, see Figure 4-Figure 7 As a specific embodiment of the film and television light provided in an embodiment of the present application, the film and television light further includes a first elastic member 8, one end of which is connected to the push rod 2, and the other end of the first elastic member 8 is connected to the front wall 11. When the external force applied to the second end of the bracket 3 disappears, the first elastic member 8 is used to drive the end of the push rod 2 away from the bracket 3 to extend out of the first through hole 111.

[0083] In one possible implementation, a pressure spring can be used as the first elastic member 8. The pressure spring can be sleeved on the push rod 2, with one end of the pressure spring connected to the middle portion of the push rod 2, and the other end of the pressure spring connected to the end of the first through hole 111 facing the interior of the housing 1. In another possible implementation, a tension spring can be used as the first elastic member 8, with one end of the tension spring connected to the middle portion of the push rod 2, and the other end of the tension spring connected to the end of the first through hole 111 facing the exterior of the housing 1.

[0084] In some embodiments, see Figure 3-Figure 6 As a specific embodiment of the film and television light provided in the present application, the push rod 2 is provided with a protrusion 21 along its circumference. A limiter 13 is provided on the front wall 11, and the limiter 13 is located between the inclined section 31 and the protrusion 21. The first elastic member 8 is sleeved on the push rod 2, with one end of the first elastic member 8 connected to the protrusion 21 and the other end of the first elastic member 8 connected to the limiter 13.

[0085] Through the above arrangement, the first elastic member 8 is sleeved on the push rod 2 and the two ends of the first elastic member 8 are respectively against the limit member 13 and the protrusion 21, which can prevent the first elastic member 8 from falling out of the first through hole 111, thereby improving the reliability of the connection between the first elastic member 8 and the push rod 2 and the shell 1.

[0086] Illustratively, the stopper 13 can be a sheet-like structure, and its shape can be any suitable shape, such as rectangular or circular. The edge of the stopper 13 can be fastened to the housing 1 near the first through-hole 111 using screws, thereby securing the stopper 13 to the end of the first through-hole 111 facing the interior of the housing 1. It will be appreciated that the portion of the stopper 13 covering the first through-hole 111 is provided with a hole for the push rod 2 to pass through. The end of the push rod 2 facing the interior of the housing 1 passes through the stopper 13 and is connected to the slider 4.

[0087] In other embodiments, the limiting member 13 may be two spaced-apart strip-like structures. The two strip-like structures may be disposed at one end of the first through-hole 111 facing the interior of the housing 1. The two strip-like structures may be formed integrally with the housing 1 through a one-step molding process. The push rod 2 may pass through the space between the two strip-like structures, with the other end of the first elastic member 8 respectively abutting against the two strip-like structures. This is not intended to be a single limitation.

[0088] Figure 7 As shown, the protrusion 21 is an annular protrusion protruding outward from the middle of the push rod 2. In other embodiments, the protrusion 21 can also be a block-shaped protrusion protruding outward from the middle of the push rod 2, which is not limited to this.

[0089] In some embodiments, see Figure 3-Figure 7 As a specific embodiment of the film and television lamp provided in the embodiment of the present application, the film and television lamp also includes a second elastic member 9, one end of the second elastic member 9 is connected to the bracket 3, and the other end of the second elastic member 9 is connected to the side wall 12. The extension direction of the second elastic member 9 is parallel to the first connecting portion 72, and the second elastic member 9 is used to reset the sliding stroke between the inclined section 31 and the push rod 2.

[0090] It is understood that when the external force acting on the second end of the bracket 3 disappears, the bracket 3 can be reset by the elastic force of the second elastic member 9, that is, when the user releases the push button 7, the push button 7 can be automatically reset. It is understood that when the user releases the push button 7, the bracket 3 moves toward the second through hole 121 under the elastic force of the second elastic member 9. During this movement, the bracket 3 drives the push button 7 and the bracket 3 to move synchronously, achieving the synchronous reset of the push button 7 and the bracket 3. In addition, during the reset process of the bracket 3, under the elastic force of the first elastic member 8, the end of the push rod 2 facing the interior of the housing 1 slides on the inclined section 31 toward the first end of the bracket 3, causing the end of the push rod 2 facing the exterior of the housing 1 to gradually extend from the first through hole 111, achieving the synchronous reset of the push rod 2.

[0091] In other embodiments, the second elastic member 9 is sleeved on the first connecting portion 72 or the second connecting portion 73. The second elastic member 9 may be a spring. Accordingly, a stopper is provided in the second through hole 121 to abut against one end of the spring, and the other end of the spring abuts against the pressing portion 71. When the user releases the push button 7, the push button 7 is reset under the elastic force of the spring, and the bracket 3 and the push button 7 are simultaneously reset.

[0092] In some embodiments, see Figure 5-Figure 7 The second connecting section 33 is provided with a bending section 34 at one end away from the first connecting section 32, and a connecting hole 341 is opened on the bending section 34. The second elastic member 9 is located on the side of the first connecting portion 72 away from the second connecting portion 73, and one end of the second elastic member 9 is connected to the connecting hole 341, and the other end of the second elastic member 9 is connected to the side wall 12.

[0093] A tension spring can be used as the second elastic member 9, and a hook is provided at one end of the tension spring and a connecting ring is provided at the other end. A connecting column 14 protruding outward is provided on the second through hole 121, and the axis of the connecting column 14 is parallel to the light output direction of the movie light. During the assembly process of the tension spring, the hook of the tension spring can be hung on the connecting hole 341 of the bent section 34, the connecting ring of the tension spring can be sleeved on the connecting column 14, and a bolt is tightened on the end of the connecting column 14 facing the interior of the housing 1 to prevent the connecting ring of the tension spring from falling off the connecting column 14. Of course, if the inclined direction of the inclined section 31 changes, a compression spring structure can be used.

[0094] The above arrangement facilitates the assembly of the second elastic member 9 and ensures the reliability of the connection between the second elastic member 9, the housing 1, and the bracket 3. In addition, the second elastic member 9 is spaced apart from the push button 7, so that the second elastic member 9 does not affect the stability of the push button 7 sliding in the second through hole 121.

[0095] In some embodiments, see Figure 3 、 Figure 4 and Figure 7 A limiting column 112 is provided on the front wall 11 and protrudes toward the first connecting section 32. A notch 322 is opened on the first connecting section 32 for the limiting column 112 to extend into.

[0096] When the external force applied to the bracket 3 disappears, the bracket 3 can be reset. The limit post 112 cooperates with the notch 322 on the first connecting section 32 to limit the maximum travel of the bracket 3 toward the side wall 12, preventing the bracket 3 from moving too far toward the side wall 12 and interfering with other components inside the movie light.

[0097] Among them, the limiting column 112 can be made into an integral part with the shell 1 through a one-time molding process. The cross-sectional shape of the limiting column 112 can be any suitable shape such as circular or polygonal. Accordingly, the shape of the notch 322 matches the cross-sectional shape of the limiting column 112.

[0098] As a film and television light, the present application may also include light sources, other housings, circuit boards, fasteners and other components, which will not be described in detail here.

[0099] The above are merely optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
